I need the sign between the (2/5)x and the 9
This means 900÷1000 because 10 to the power of 3 is 1 and 3 zero which is 1,000. The answer will be 0.9
Question 1:
For this case we have an equation of the form:

Where,
- <em>k: inverse variation constant.
</em>
Then, substituting values we have:

From here, we clear the value of k.
We have then:

Answer:
the constant of inverse variation is:

Question 2:
For this case we have:

Where,
- <em>k: constant of variation.
</em>
Then, substituting the value of the constant we have:

We now substitute the value of x:

Answer:
the value of y when x = 4 is:

The interpretation of the point of intersection of the curves is (c) they give a solution to the equation 5x - x^2 = 3x - 0.5x^2
<h3>How to interpret the points of intersection?</h3>
The graph of the two functions alongside their equations are the given parameters of this question
The functions are given as:
f(x) = 5x - x^2
g(x) = 3x - 0.5x^2
When the graphs of two curves or lines intersect on a coordinate plane, it means that the point of intersection represents where the graphs have equal value
In this case, it represents
f(x) = g(x)
Substitute the known values in the above equation
5x - x^2 = 3x - 0.5x^2
So, the interpretation of the point of intersection of the curves is (c) they give a solution to the equation 5x - x^2 = 3x - 0.5x^2

Answer:
8.778 or 8.8
Step-by-step explanation:
20% of 43.89 is 8.778
math: 43.89*(20/100) = 8.778
